Rattle in front brakes of '98 GC
Bought this '98 5.9 Limited last year for my wife. In Ouray last summer there
was a rattle in the front end when off-road except when the brakes were
applied.
I replaced pads. Still rattled. I replaced mounting pins. No change. I
replaced both calipers and rotors (had some pulsating) and pins again, but it
still rattles, unless the brakes are applied. Even a slight touch on the
pedal, not enough to slow at all, quiets it down.
It used to only rattle over bumps, but it's getting so it sets up a vibration
at slower speeds on pavement now that rumbles until higher speeds are reached,
or the brake is applied.
What the heck?

Bearings, ball joints, shocks, and another front end part?

A little on the brake will tighten up the whole front end, especially the
suspension arms. Although those usually make a pop-pop-pop noise associated
with acceleration and braking.
The other possibility is your brakes arn't shimmed properly.
Also check your antisway bar mounts. These can make creak/groan noises and
rattles. http://members.***.net/wilsond/swaybar/

Bearings don't rattle, they rumble or groan, I think.
Ball joints have pressure on them except when bouncing, which should keep them
from rattling when they're on the ground.
Shocks shouldn't stop rattling when brakes are applied.
I don't know of another front end part that tightens up under braking except
for the control arms.
